Run-Time Services for Hybrid CPU/FPGA Systems on Chip
Modern FPGA devices, which include (multiple) processor core(s) as diffused IP on the silicon die, provide an excellent platform for developing custom multiprocessor systems-on-programmable chip (MPSoPC) architectures. As researchers are investigating new methods for migrating portions of applications into custom hardware circuits, it is also critical to develop new run-time service frameworks to support these capabilities. Hthreads (HybridThreads) is a multithreaded RTOS kernel for hybrid FPGA/CPU systems designed to meet this new growing need. A key capability of hthreads is the migration of thread management, synchronization primitives, and run-time scheduling services for both hardware and software threads into hardware. This paper describes the hthreads scheduler, a key component for controlling both software-resident threads (SW threads) and threads implemented in programmable logic (HW threads). Run-time analysis shows that the hthreads scheduler module helps in reducing unwant...
